# C64-PSU
|
|
A C64/C128/Vic20/Plus4 PSU
|
|
This is a full replacement PSU with modern electronics that won't kill your computer when it gets bad.. the original PSU's short input to output, when they break, feeding approx 10v.
|
|
While it is possible to use wall warts, this design is created to be easy to diy, somewhat pretty and closer to the old designs with off the shelf items.
|
|
|
|
Greetz to Trap/Bonzai for being the source of inspiration to create this.
|
|
|
|
The PSU can be used for the C64 even with i.e. 1541 Ultimate and Vic20, and it's powerful enough to feed the C128 and/or 17xx REU.
|
|
|
|
All parts can be bought at [tme.eu](https://www.tme.eu/), and the pcb has been designed with parts from there.
|
|
A few parts like the DIN connector and fuse socket can be aqcuired from ebay where they're much cheaper.
|

|
*If you are a reseller, and use my designs, though the projects are open source, I'd like to ask you to donate a small amount of money, to cancer research for each sold device.*

The Mean Well IRM-20-5 is Short circuit / Overload / Over voltage protected (pdf's from Mean Well are in the documentation folder).

|
**The trafo is a 230v trafo, so countries that use 115v will need a different trafo.**
|
|
|
|
If you want to add an on/off switch, the easiest might be a switch on the 230v cable, or a round one, the round one is easiest to make holes to -by drilling-, rather than cutting a square one. But that is entirely up to you :-) .

|
The gerber files which is the zip file found in [hardware/eagle](https://github.com/Retro-Commodore/C64-PSU/tree/master/Hardware/Eagle Gerber) can be uploaded as is to PCB manufacturing companies like [JLCPCB](http://jlcpcb.com).
|
|
|
|
The PCB is created with Eagle which has a limiting size of 100x100mm (or is it 100x80mm?). And the PCB is within this size.
|
|
The newest version of KiCAD should be able to import the eagle files, in case you prefer this.

|
**TODO**
|
|
* Add possibility to use PTC (one has to be sourced first), if you read this and know of one already please don't hesitate to add a ticket with the info. You'll providing the community a service :-)
